Organic synthesis mind map

(0)
A comprehensive mind map on organic synthesis which students can use to revise the theory Students can use the resource to produce routes for organic synthesis required in A-Level Chemistry exams.
Atomic structure and periodic table cards

Atomic structure and periodic table cards

(0)
A playing cards activity which has questions on atomic structure and periodic table. Students can play different card games which also test their knowledge. Students liked playing black Jack where they could only twist and receive a card if they got the question right on the back of the card. There are several games that my students enjoyed playing with this resource. Foundation and higher game cards are included.
Our evolving atmosphere

Our evolving atmosphere

(0)
A bundle of resources on the atmosphere. A rank the definition activity encourages class discussion on how to define the atmosphere. Also included, a group relay activity where students in their groups have to answer questions on how the Earth's atmosphere has changed from the past till present. Students answer each question in turn and can only have a go at the next question once the teacher has confirmed their answer is correct. The group quickest to complete the questions are the winners. Students love these relay activities, it encourages competition and team work and typically takes 10 mins to complete.
Empirical formulae

Empirical formulae

(0)
A bundle of three resources on the A-Level concept calculating empirical formulae. The resources include a differentiated calculations sheet (with answers) with each section increasing in difficulty. A class relay activity is included, which involves students working in groups to solve empirical formula problems. Both resources combined encourages active participation and takes about an hour to complete.

Topic 18A Arenes flash cards

(0)
A collection of more than 100 flash cards on the Structure and reactions of Benzene. Suitable for the new A-Level 2015 syllabuses. Each cue card has a question with the answer on the back. An excellent revision resource for students, takes just 5 minutes to print out the cards and cut them up.
Electrolysis of solutions activity
polarity24polarity24

Electrolysis of solutions activity

(0)
KS4 Resource on electrolysis Instructions: There are 16 boxes of questions. Print off in various colours and then cut out so they are in stacks stapled Q1 – 16. Each team is allocated a different colour. They rip a question off at the front of the class and take it back to their team to answer it. They then bring it back to teacher at front who marks it. If correct they can move onto the next Q. If incorrect they return to their group and re-attempt. First team to complete all Qs wins.
Grignard reactions
polarity24polarity24

Grignard reactions

(0)
A lesson on Grignard reactions consisting of a PowerPoint and a worksheet. Suitable for all A-level exam boards. covers the 3 steps in the Grignard reaction and includes information on how to get the reaction started, solvent, conditions and relevant equations. The editable worksheet comes with answers.
Entropy - calculating total entropy
polarity24polarity24

Entropy - calculating total entropy

(1)
A revision resource with questions on calculating entropy of the system, surroundings, total entropy and entropy of solution for dissolving ionic salts. Answers are included within the editable worksheet which allows students to mark their work and monitor their progress. The questions get more difficult as each section progresses.
Redox Ecell game

Redox Ecell game

(0)
I used this with my year 13 class and they loved it. An excellent revision resource. Students have to answer a question on Ecell if they land on a star. Question cards on Ecell are included in this resource.
Amount of substance (1 of 2)
polarity24polarity24

Amount of substance (1 of 2)

(1)
An A-Level Chemistry resource on calculating Amount of substance (Moles). The worksheet is differentiated with each section increasing in difficulty. Answers are included with each section so that students can check their progress. This is the first half of this resource, the 2nd half is also available on this website with 2 more pages on atom economy, empirical formulae, percentage yield etc. The complete set has 16 sections in total. If you like this resource there are others of a similar format on calculating entropy, pH, Kc, Kp, Grignard reagents, inorganic formulae, Ecell, pV = nRT etc. These sheets conrain examples of every type of exam questions atudents may face.
Transition metal reactions
polarity24polarity24

Transition metal reactions

(0)
PowerPoints going over the reactions of Transition metals, deprotonation, ligand exchange. relevant for A-level Chemistry. Also includes another Power Point on the colours of the Transition metal precipitates.
Thermal decomposition of carbonates and nitrates (group 1 and 2)
polarity24polarity24

Thermal decomposition of carbonates and nitrates (group 1 and 2)

(0)
Eight resources on the thermal decomposition of the group 1 and 2 nitrates and carbonates. The first resource is a differentiated worksheet with the questions designed around the style of AQA, Edexcel and OCR exam papers and test students on every aspect of the topic including the reactions, observations, trends, theory of charge density/polarisation and finishes with a few questions on how we measure it experimentally. I looked at exam papers from all three exam boards when designing this resource so that it provides comprehensive coverage for my students. Answers are included. There is also a resource which goes through the qualitative observations associated with thermal decomposition of the carbonates and nitrates (what’s observed e.g limewater goes cloudy, brown gas of Nitrogen dioxide etc). I have also included a spider diagram of the reactions/observations and Power Points which explain the science behind it. There is then a hexagon activity and a challenge grid, both designed at stretching & challenging the students.
Electrode potentials and electrochemical cells

Electrode potentials and electrochemical cells

(1)
This is a differentiated A-level chemistry revision resource covering the different types of Ecell questions. There are 8 sections, each one increasing in difficulty. The resource is editable and the markscheme is provided. Could be used in a revision lesson at the end of the topic. There is also useful tips on how to calculate Ecell and writing of cell diagrams. There is one of every type of Ecell question that students could be tested on in an exam. Takes about 2 hours to complete. I also have several other resources like this one in my shop on moles, pV=nRT, redox titrations, entropy, Equilibrium Kc & Kp, pH calculations and also buffer calculations. Each one covers all the different types of calculations they need to revise for the exams.
